Andrea Maria Piana 6acb34bab7 Allow setting up wallet with new config
This commit does a few things:

1) Extend create/import account endpoint to get wallet config, some of
   which has been moved to the backend
2) Set up a loop for retrieving balances every 10 minutes, caching the
   balances
3) Return information about which checks are not passing when trying to
   join a token gated community
4) Add tests to the token gated communities
5) Fixes an issue with addresses not matching when checking for
   permissions

The move to the wallet as a background task is not yet complete, I need
to publish a signal, and most likely I will disable it before merging
for now, as it's currently not used by desktop/mobile, but the PR was
  getting to big

How to write migrations?

We only write up migrations, down migrations are not always possible in sqlite or too complex/too expensive. For example to remove a column you would have to duplicate the table, copy over the data, delete and recreated. This can be very expensive for some tables (user_messages for example), so should not be attempted.

Notes

One issue we faced multiple times is that updates to user_messages can be very expensive, leading to slow upgrade times and interrupted migrations. So avoid writes if not necessary.
